Methyl iodide → Methyl 1-(p-tolyl)cyclopropanecarboxylate

Participants

Reaction Steps

To a solution of 1-(p-tolyl)cyclopropanecarboxylic acid (900 mg, 5.1 mmol) in acetonitrile (20 mL) was added DBU (917 μL) followed by methyl iodide (1.91 mL). The resulting solution was heated at reflux overnight, and then diluted with AcOEt. The mixture was washed with a 0.5 N HCl solution, a saturated solution of NaHCO3, and brine, dried on MgSO4, and concentrated. The resulting colorless oil was purified by chromatography on silica gel (Hexane/ethyl acetate 9/1) to afford the title compound as a colorless oil (622 mg, 64%).
